Genomic Analysis of Leptolyngbya boryana CZ1 Reveals Efficient Carbon Fixation Modules.

ABSTRACT: Cyanobacteria, one of the most widespread photoautotrophic microorganisms on Earth, have evolved an inorganic CO₂-concentrating mechanism (CCM) to adapt to a variety of habitats, especially in CO₂-limited environments. Leptolyngbya boryana, a filamentous cyanobacterium, is widespread in a variety of environments and is well adapted to low-inorganic-carbon environments. However, little is currently known about the CCM of L. boryana, in particular its efficient carbon fixation module. In this study, we isolated and purified the cyanobacterium CZ1 from the Xin'anjiang River basin and identified it as L. boryana by 16S rRNA sequencing. Genome analysis revealed that L. boryana CZ1 contains β-carboxysome shell proteins and form 1B of Rubisco, whi
